Symptoms of A Bad Oven Temperature Sensor
Your oven is the heart of the kitchen. It roasts, bakes and warms your favorite foods with ease. Today's oven models are full of convenient features that make them practically maintenance-free appliances. However, issues can arise that point to a bad part. Consider the symptoms and solutions to a bad oven temperature sensor. Your oven can serve the family with tasty foods once again.
Longer Than Usual Cooking Times
A common complaint among oven users is long cooking times. You're accustomed to cooking a cake or chicken at a specific temperature for a set period of time. This time seems to be lengthening with each meal. Failed oven temp sensors are probably the culprit.
The sensor isn't gauging the proper temperature. In fact, it might be intermittently working. Pay close attention to the cooking times that you know are a fact. Any significant change, such as 10 or 20 minutes, is cause for concern. The sensor may not be consistently functioning anymore.
Your family might cook chicken several times a month. It turns out moist and perfectly roasted every time. One day, however, the chicken is almost raw in the middle. The household cooks didn't do anything wrong. It's possible that the oven temp sensors malfunctioned.
The sensor may be functioning, but it's inaccurate. It's only heating the oven to a fraction of the required temperature. You see the oven's temperature gauge as correct, but the sensor has other plans. Undercooked foods are often the most noticeable symptom of a bad sensor.
Uneven Cook on Your Meals
Bake a cake or cookies, and the oven should evenly warm the food as it sets. A failed sensor changes this simple fact, however. You might discover that half of the food is cooked while the other half is raw. This scenario is particularly concerning when it comes to meat and safe cooking temperatures.
All modern ovens should have uniform heat across their interiors. This feature is thanks to the included fans in the design. Don't chalk up uneven cooking to bad luck. Check your sensor for any issues.
A serious symptom of a bad sensor is overheating. You set the oven to 350-degrees Fahrenheit, and it's rapidly rising to 450-degrees F. Immediately shut off the oven. This overheating scenario can quickly grow into a serious problem.
You may be able to keep tabs on the rising heat by using an independent temperature gauge placed in the oven. Simply set the oven on a low temperature, such as 250-degrees F., and watch the gauge. You will need to replace the sensor as soon as possible otherwise.
Solving the Problem With a Troubleshooting Tip
When you've isolated the problem to a bad oven temperature sensor, solving the issue is your top priority. This part hasn't necessarily gone bad, however. It might require a basic adjustment.
Take a look inside your deactivated oven. The sensor is usually visible near the back of the space. If the sensor has bent toward the oven's wall, it could be touching hot metal during use.
Adjust the sensor out from the wall. It may be close to the wall but not touching it. Turn the oven on again. Test it for an even and accurate temperature. In many cases, this troubleshooting tip is your solution.
Trying out an Ohmmeter
A bad oven temperature sensor can also be pinpointed by checking the resistance at its probe ends. Wait for the oven to be completely cool for this troubleshooting maneuver. Use an ohmmeter to test the sensor probe on both ends. A strong reading should hover around 1,100 ohms.
If you encounter any values below or above 1,100 ohms, the sensor is bad. It uses this resistance in order to warm up the oven to its proper temperature. Swapping out the sensor with a new part should give you the proper resistance needed for reliable operations.
Discovering a Combination of Problems
In a perfect world, a bad oven temperature sensor would be your only problem. However, it's possible for several parts to be bad.
Consider these parts that can be combination problems during oven heating, including:
Any combination of issues from these parts can simulate the symptoms of a bad sensor. Pay careful attention to the particular problems that are plaguing the oven. Use this information to narrow down the parts problem. Contacting oven professionals may be necessary in this case.
The Oven-Board Failure
Behind the oven's control panel is a printed circuit board or PCB. It's designed to last for the life of the appliance, but problems can arise. Component shorts and surges will quickly break the part down. The sensor ends up being your last problem of the day. Oven boards must be in good working order to control any features.
Depending on the failure type, the board may or may not be repairable. A professional must look at it. Failed, isolated components on an otherwise healthy board can be normally swapped out with careful strategies.
Outright burns on the board means that it must be replaced. There's too much damage to make a repair possible.
